At the time I didn't really think about that, but as time went on it came back to me and I thought about it, and realized she was right. In fact, the last time I bought anything for myself that wasn't a 100% strict necessity was April of 2015, when I bought that SSD that I put into the laptop.
I later recounted my thinking to her, and explained it thus: because of my upbringing, my conscience is over-powerful, and frequently vetoes things like that. I adopted this snooty, disdainful, German voice, and said:
"Vy are you tinkink of buyink a microcontroller? If you haf time and energy to tinker vith electronics, vy don't you paint de livink room?"
Mrs. Fungus: AHHH HA HA HA HA HA
"You shouldn't be goink out for Chinese takeout. You bought food the other day; you should cook zat insteat. Takeout is for people who vork. Vy don't you get another job, you lazy man?"
And, "Vy should you have any fun? Fun is for people who haff money. You do not haff any money. Forget your stupid dreams and vork."
And, "Oh, you are tiret? Everyvun is tiret. Stop being such a layabout. You could vork two jobs if you really vanted to; you are just being lazy."
And on and on, in that vein.
...if I get to the point--working full-time--where $35 breaks me, I'm screwed anyway. But the microcontroller (whatever form it takes) will be a reward to myself for getting the basement cleaned.

Gas hit $1.90 today. What the fuck.
ADDENDUM: Here's why; the bond market coughed up a bucket of dicks so people bought commodities, and sent the prices skyrocketing. We still have an oil glut and we're still running out of space to store all the oil being produced, but because a bunch of banksters lost their shit, gas has risen thirty cents a gallon for the second time in as many weeks.
